average power costs in the usa are 15ct/kwh. these strips are about 30% less efficient than modern strips. so lets run 100$ of the cheap strips against 200$ of modern strips. we run them on a 200w driver. we flower only with this panel so it needs 2,4kwh per day. the modern ones are 30% more efficient so we can dim down the driver and we only need 1,68 kwh per day to get the same output. so our new panels cost us 0,36$/0,252$ per day to run.
so let‘s calc with that.
100 + 0,36x = 200 + 0,252x | -100 -0,252x
0,108x = 100 | :0,108
x = 925,92
—> those 10$ cuter strips are "worth it" after 926 days. wow. so much better
